The coast, also known as the coastline, shoreline or seashore, is defined as the area where land meets the ocean, or as a line that forms the boundary between the land and the coastline. Shores are influenced by the topography of the surrounding landscape, as well as by water induced erosion, such as waves. The geological composition of rock and soil dictates the type of shore which is created. The Earth has around 620,000 kilometres (390,000 mi) of coastline. Coasts are important zones in natural ecosystems, often home to a wide range of biodiversity. On land, they harbor important ecosystems such as freshwater or estuarine wetlands, which are important for bird populations and other terrestrial animals. In wave-protected areas they harbor saltmarshes, mangroves or seagrasses, all of which can provide nursery habitat for finfish, shellfish, and other aquatic species. Rocky shores are usually found along exposed coasts and provide habitat for a wide range of sessile animals and various kinds of seaweeds. In physical oceanography, a shore is the wider fringe that is geologically modified by the action of the body of water past and present, while the beach is at the edge of the shore, representing the intertidal zone where there is one. Along tropical coasts with clear, nutrient-poor water, coral reefs can often be found between depths of 1–50 meters.
Longshore drift from longshore current is a geological process that consists of the transportation of sediments along a coast parallel to the shoreline, which is dependent on the angle of incoming wave direction. Oblique incoming wind squeezes water along the coast, and so generates a water current which moves parallel to the coast. Longshore drift is simply the sediment moved by the longshore current. This current and sediment movement occur within the surf zone. The process is also known as littoral drift.
Barrier islands are a coastal landforms—a type of dune system and sand island—where an area of sand has been formed by wave and tidal action parallel to the mainland coast. They usually occur in chains, consisting of anything from a few islands to more than a dozen. They are subject to change during storms and other action, but absorb energy and protect the coastlines and create areas of protected waters where wetlands may flourish. A barrier chain may extend for hundreds of kilometers, with islands periodically separated by tidal inlets. The largest barrier island in the world is Padre Island of Texas, United States, at 113 miles (182 km) long. Sometimes an important inlet may close permanently, transforming an island into a peninsula, thus creating a barrier peninsula, often including a beach, barrier beach. Though many are long and narrow, the length and width of barriers and overall morphology of barrier coasts are related to parameters including tidal range, wave energy, sediment supply, sea-level trends, and basement controls. The amount of vegetation on the barrier has a large impact on the height and evolution of the island.
The National Estuarine Research Reserve System is a network of 30 protected areas established by partnerships between the National Oceanic and Atmospheric Administration (NOAA) and coastal states. The reserves represent different biogeographic regions of the United States. The National Estuarine Research Reserve System protects more than 1.3 million acres of coastal and estuarine habitats for long-term research, water-quality monitoring, education, and coastal stewardship.
The Long Term Ecological Research (LTER) Network consists of a group of over 1800 scientists and students studying ecological processes over extended temporal and spatial scales. Twenty-eight LTER sites cover a diverse set of ecosystems. It is part of the International Long Term Ecological Research Network (ILTER). The LTER Program was established in 1980 and is funded by the U.S. National Science Foundation. Data from LTER sites is publicly available in the Environmental Data Initiative repository and findable through DataONE search.
The University of Georgia Marine Institute (UGAMI) is a nearshore ecological and geological research station located on Sapelo Island off the coast of Georgia in the United States. This island lies between the Atlantic Ocean and a pristine salt marsh. A ferry takes passengers from Meridian to Sapelo Island. The Island has fewer than 100 full-time residents. The Institute was created in 1953 and is currently a unit of the University of Georgia's Office of Research. The Institute is 280 miles southeast of the University of Georgia's main campus in Athens. UGAMI is world-renowned for its research on coastal marine and estuarine ecosystems.
National Ecological Observatory Network (NEON) is a large facility program operated by Battelle Memorial Institute and funded by the National Science Foundation. In full operation since 2019, NEON gathers and provides long-term, standardized data on ecological responses of the biosphere to changes in land use and climate, and on feedback with the geosphere, hydrosphere, and atmosphere. NEON is a continental-scale research platform for understanding how and why our ecosystems are changing.
The Volgenau Virginia Coast Reserve is a biosphere reserve created by The Nature Conservancy in the early 1970s. It consists of 40,000 acres across 14 of the Virginia Barrier Islands along the Atlantic coast of the Virginia portion of the Delmarva Peninsula, including Parramore Island, Hog Island, Virginia, Smith Island, Virginia, Assawoman Island, and Metompkin Island. These barrier islands play an important role in sheltering the mainland portions of the Eastern Shore of Virginia from the impact of coastal storms and are important for breeding and migrating beach nesting and colonial waterbirds, including piping plovers. It also serves as the research location for the Virginia Coast Reserve Long-Term Ecological Research project.
Hog Island is one of the Virginia Barrier Islands located southeast of Exmore in Northampton County, Virginia, and is a part of the Virginia Coast Reserve of The Nature Conservancy. The island, then known as Machipongo Island was first settled in 1672 by a group of 22 English colonists. The island was later abandoned and remained uninhabited until around the time of the American Revolution when it was resettled. In the late 1800s, at least five lavish hunting and fishing clubs that primarily catered to wealthy sportsmen from the Northeast were established on Virginia's barrier islands; one of the largest and most lavish of these clubs was in the town of Broadwater, Virginia, on Hog Island.
San Elijo Lagoon Ecological Reserve is one of the largest remaining coastal wetlands in San Diego County, California, United States.
Bacalar Chico National Park and Marine Reserve (BCNPMR) is a protected area and UNESCO World Heritage Site on the northern part of Ambergris Caye in Belize.
The South African Environmental Observation Network (SAEON) is a science network of people, organisations and, most importantly observation platforms, that perform Long-Term Ecological Research (LTER) in South Africa and its surrounding oceans. The SAEON is of global importance as an innovative approach in ecology to understand environmental change and to determine the impact of anthropogenic forces at multiple scales but it is a remarkably complex challenge to statistically discern between ubiquitous natural variability and exogenous forcing. The SAEON constitutes a national government response to the World Summit on Sustainable Development (Earth Summit 2002) and is a component of the GEO (Group on Earth Observations). The SAEON has become the leader in environmental science and observation in South Africa, but has been criticised for taking a long time to establish, a situation which was inevitable in view of SAEON's multiple stakeholder corps. It has also been raised that the cost of replicated experimental treatments across SAEON sites will be high.
Coastal hazards are physical phenomena that expose a coastal area to the risk of property damage, loss of life, and environmental degradation. Rapid-onset hazards last a few minutes to several days and encompass significant cyclones accompanied by high-speed winds, waves, and surges or tsunamis created by submarine (undersea) earthquakes and landslides. Slow-onset hazards, such as erosion and gradual inundation, develop incrementally over extended periods.
The H.J. Andrews Experimental Forest, commonly referred to as Andrews Forest, is located near Blue River, Oregon, United States, and is managed cooperatively by the United States Forest Service's Pacific Northwest Research Station, Oregon State University, and the Willamette National Forest. It was one of only 610 UNESCO International Biosphere Reserves, until being withdrawn from the program as of June 14, 2017, and a Long Term Ecological Research site. It is situated in the middle of the Western Cascades.
